I had Xcode 4.1 preview 5 working fine but decided to upgrade to the final xcode 4.1 thru the App store. I uninstalled Xcode first…
sudo /Developer/Library/uninstall-devtools –mode=all
Then installed Xcode thru the app store and rebooted.
I also removed RVM completely but… now whenever I try and install a version of Ruby it fails. In the error file i get this:
[2011-07-27 18:29:25] ./configure --prefix="/Users/holden/.rvm/usr"

configure: error: in `/Users/holden/.rvm/src/yaml-0.1.4':
configure: error: C compiler cannot create executables
See `config.log' for more details
There is no gcc-4.2 or any other gcc in the /usr/bin directory.
What's up with Xcode?

Apparently even after downloading and "installing" XCode from the Appstore and despite the long process after downloading where it appears to install it and the words "Installed" eventually become displayed next to it in the store. You must still manually install it again within your applications folder before it will work.
Odd.
